More about this voice

One effect does almost all of it

A ring modulator multiplies your voice by a steady tone. At 30 Hz that tone is too low to hear as a note, so it chops the voice into a rapid, grating flutter. The Robot slider on this page is that effect.

Part	Setting	What you hear
Ring modulator	Robot 30 Hz, 100% mix	The whole voice fluttering, none of it left clean
Overdrive	Distortion 0.5, 70% mix	A harsh, shouted, speaker-in-a-casing edge
Casing	Bass cut below 250 Hz, treble cut above 5 kHz, midrange +5 dB around 1.5 kHz	A hard, nasal, boxed-in tone

Deliver it in staccato

Split words into syllables and give each one equal force, with a tiny gap between them.
Start a line level and climb in pitch and volume toward the end, as if the anger is building.
Pitch is left at 0, so raise your own voice a little and make it nasal.
Use commands, threats and reports to a superior, and repeat the key verb.

Which buzz to pick

30 Hz with distortion, the main clip: the full harsh voice, for commands.
Ring modulator at 50 Hz: a faster, angrier buzz. It suits a more agitated Dalek.
Distortion off: only the ring modulator, as the effect was first made. Cleaner, and better for longer dialogue.

Free Dalek voice changer FAQ

Is this the same effect the TV series uses?

It is the same kind of effect, a ring modulator at about 30 Hz. It isn't the show's audio or an official voice: you give the performance and the browser applies the modulation.
